Problem

When using an HTTP Proxy server for authenticating your Web requests, the basic authentication may fail with the following exception:

HTTP Proxy Authentication Fails When Using Java 8 Update 111 or Later

This exception occurs because proxies requiring Basic authentication when setting up a tunnel for HTTPS no longer succeeds by default starting from Java 8 Update 111.

Solution

To solve this issue, you need to reactivate the authentication scheme by removing Basic from the jdk.http.auth.tunneling.disabledSchemes networking property, or by setting a system property of the same name to "" ( empty ).

To reactivate the authentication scheme from Monitoring Studio X:

  1. Log in to the Monitoring Studio X Web Interface
  2. Go to Agent > Java Settings
  3. In the JVM Arguments field, enter:
-Djdk.http.auth.tunneling.disabledSchemes=""
